Texas Instruments (TI) has introduced the first Wireless Power Consortium (WPC) v1.2 Qi-certified 15-W wireless power transmitter. The bq501210 enables 84 percent system efficiency with significantly less thermal dissipation than traditional wireless power devices. The transmitter supports multiple fast-charging protocols and offers an array of flexible and customizable features such as personal electronics, medical and space-constrained industrial applications.
Industrial end equipment such as electronic point-of-sale devices and handheld medical equipment reap the benefits of 15-W wireless power. This breakthrough in technology enables connector-less models and reduces overall end-application size by helping eliminate the need for bulky wiring.
Features and benefits of the bq501210 include: System efficiency at 84 percent: Fixed-frequency operation helps achieve the highest 15-W efficiency as well as reducing EMI. Fast-charging capability: Fast-charge negotiation with mobile devices enables the transfer of up to 10W to compatible receivers, including existing fast-charging devices on the market. Wide-voltage aptitude: The High-Voltage Dedicated Charging Port (HVDCP) protocol negotiates with capable ac-dc wall adapters to adjust the input voltage. The rail control output provides power to deliver a full 15W with inputs between 15V and 19V, and enables lower power operation, such as 5W, with inputs as low as 5V.
Engineers can speed time to market and easily evaluate the new device’s features and performance with the bq501210 evaluation module (EVM). The bq501210EVM-756 is available for US$149.
The bq501210 transmitter is shipping in volume production now and is available through the TI store and the company’s authorized distribution network. The bq501210 comes in a 9-mm-by-9-mm very thin quad flat no-lead (VQFN) package and is priced at US$3.75 in 1,000-unit quantities.
